Facing problem in re-deploying the orchard site in windows azure environment

We have developed a site that uses orchard CMS. The site was deployed first time on the windows azure environment and the required set-up information was provided in the Orchard set-up screen. Now with some modification, I am trying to re-deploy the site but
this time again the Orchard CMS set-up screen is popping up which I wasn't expecting. If I fill the setting it might override the previous one which I don't want. Has anyone faced a similar situation? How can poping up set-up screen be avoided on re-deployment?
Any help will be much appreciated.
